1 Claim. (Cl. 1976.4)

This invention relates to a pocket size check writer and has for anobject the provision of a pocket size check writer which is designed toprevent forgery. or other falsification of letters or figures printed ona check or securities, and which may be simply operated by hand.

This invention provides a pocket size check writer comprising a basestand provided with a paper feeding mechanism, and an operating leverhaving a printing wheel and ink applying means and adapted to be openedautomatically by swinging upwardly under the action of a spring about apivot at the rear end of the base stand, said ink applying means beingsoconstructed that an ink roller is pressed against the under surface ofthe printing wheel at the open position of the operating lever and isretracted by pressing down the operating lever and said paper feedingmechanism being so constructed as to engage with the operating lever torotate a driving gear wheel over a given angle by the upward swingingmotion of the operating lever so as to move a paper feeding rod engagedwith the gear wheel overa given length.

The paper feeding mechanism comprises a check printing paper feeding rodadapted to be inserted into a transverse guide groove in the base standto. move slidably therealong, in engagement with a gear wheel pivoted onthe base stand, by a rackformed along one side-of the feeding roditself, a guide member slidably mounted on the base stand beingconnected to a drive rod having two forked ends formed integrallytherewith at its forward end, a push rod connected to the rear end ofthe guide member being arranged in opposition to the lower end of theprojecting part at the rear end of the operating lever,

said drive rod being pressed downwardly by the action of a springembedded in a cavity of the guide member so as to engage with the gearwheel by one of its forked ends, a pin fixed on the underside of thebase stand being arranged to engage with the other of'the forked ends soas to release said one forked end from engagement with the gear wheelwhereby the check printing paper is fed over a given length togetherwith the transverse feeding rod.

In order to reduce'the overall size of this check writer, the checkpaper feeding-rod may be withdrawable from a transverse groove in a base'stand and is insertable in a longitudinal slot formed in the ba sestand whereby the overall size of the check writer is reduced. f

In order to hold satisfactorily the check paper when it is printed, thecheck paper fe eding rod is provided at its outer end witha paper clipconsisting of projections and corresponding holes thereby to holdthecheck paper. The feeding rod comprises two parts fitted to each othertelescopically whereby the length of said rod may be increasedcorresponding to thetransversewidth or length of a check paper to beprinted. v p

As shown in the drawings, this pocket size check writer-consists 'of abase stand A provided at its under side with a check paper feedingmechanism and at its upper surface with check supporting and shiftingmeans, and an operating lever 3 having a printing wheel and an inkapplying roller andpivoted on a pivot 1 fixed at the rear end of thebase'stand A. i T i P The base stand A and the operating lever'B are.preferably made of plastic material, such as a synthetic resin; inorder to reduce their weight and also to facilitate their manufacture. i

' The operating lever B is shapedin the form of a casing open at it'sunderside and has a shaft 3 rotatably mounted therein at its free end.To said shaft 3 a printing wheel 2 is rigidly fixed. An operating wheel4 is fixed to an outwardly extending end of the shaft 3 and by which theprinting wheel 2 may be rotated as desired by hand. On the periphery atone side of the printing wheel 2, a series of caption letters or figurescorresponding to those on the printing wheel 2 are marked. On an upperwall of the operating lever B, an arrow 5 is marked so as to be able toselect a desired letter or figure. In order to prevent idle rotation ofthe printing wheel 2, a spring plate -6 fixed at one side to theoperating lever B engages, by its bent tip, with a gear wheel 7 formedintegrally with the printing wheel 2 To the free end of a support 8downwardly extending from an inner surface of an upper wall of theintermediate portion of the operating lever B, one end of a link 9 ispivoted by means of a pin 10. 'The other end of the link 9 is pivoted bymeans of a pin 11 to one end of each of a pair of links 12 and the otherend of the links 12'support an ink roller 13 rotatably mounted thereon.The ink roller 13 is normally urged intocontact with the periphery I ofthe printing wheel 2 by theaction of a coil spring 14 which hassufficient energy tobend the link- 12 towards the link 9. One end of alink 15 is pivoted by means of a pin 16 to the'intermediateportion ofthe link 9. The other end of the link 15 is pivoted to the upper ends ofa pair of links '17 bymeans of a pin 18. The lower ends of the links 17are pivoted by means of a pin 19.1tofor ward ends of a pair of-parts 20projecting forwardly from the rear upper portion of the base stand A.The lower endofthe link 15 directly below th Pin 18 is pressed upwardlyby the action of the upper end of a spring 21 in the form of a V-shapeand a lower free end of the spring 21 is fixed on the upper surface ofthe base stand A. Accordingly, the ink roller 13 is held in contact withthe lowermost letter or figure on the-printing wheel 2 when theoperating lever is held in an uppermost position. Also the upper ends ofthe links 17 are urged to engage lower surfaces of a pair of inclinedguide parts 22 formed integrally with the inner side of the rear end ofthe operating lever B and are guided slidably along said lower surfaceswhen the operating lever B is moved.

Therefore, the operating lever B is normally held in an opened positionas shown in Fig. 3 by the action'of the spring 21. When the operatinglever B is pressed downwardly, the upper ends of the links 17 are guidedrearwardly along the lower surfaces of the guide parts 22 so as to swingthe links 17 about the pin 19 and consequently the link 9 is swungrearwardly about the pin 10 by the link so that the ink roller 13 isretracted to be received by a lower end of a hanging abutment 23 formedintegrally with an inner side of the operating lever B. Accordingly, theprinting wheel 2 assumes a position to print upon a check paper placedon a lower matrix 24 which is fixedly embedded and has a notched surfaceto leave a series of notches on the check paper after printing. Saidposition of the printing wheel 2 is shown in Fig. 6. When the operatinglever B is released, the parts of the check writer assume the positionshown in Fig. 3.

The operating lever B has a downwardly projecting part 25 at its rearend loosely passing through an opening 26 formed at a corresponding rearend of the base stand A. This projecting part may be reinforced at itsside by a metal plate of proper form, if desired. The projecting part 25is arranged in opposed relationship to a movable plate 27 slidable in alongitudinal guide groove 28 on the underside of the base stand A. Arear end of a push rod 29 is fixed to said movable plate 27 and saidpush rod 29 is loosely passed through and adapted to be reciprocated ina supporting plate 30 formed integrally with the. base stand A. Whilethe operating lever B is being swung by the action of the spring 21 froma printing position shown in Fig. 6 to an opened position shown in Fig.3, the projecting part 25 pushes the movable plate 27 together with thepush rod 29 forwardly against the action of a spring 31 located betweenthe movable plate 27 and the supporting plate 30. To the forward end ofthe push rod 29 a guide member 32 is fixedly connected to slideforwardly and rearwardly inthe guide groove'28. In a guide slot 33formed in the guide member 32, the rear end of a drive rod 34 is pivotedby means of a pin 35 as shown in Fig. 9. Said drive rod 34 has twoforked ends 36, 37 at its forward end, and one forked end 36 is adaptedto be engaged by the action of a spring 38 with a gear wheel 39pivotally mounted on a shaft 40 which is mounted at the underside of thebase stand A. Said gear wheel 39 is prevented from idle rotation by theengagement of a tip of a. brake member 41 with the teeth of the gearwheel 39. Said brake member 41 is slidably mounted in a cavity 42 formedon the underside of the base stand A and serves tostop idle rotation ofthe gear wheel 39 by the action of a spring 43.

As above described, when the downwardly projecting part 25 of theoperating lever B pushes the push rod 29 forwards, the forked end 36 ofthe drive rod 34 engages the teeth of the gear wheel 39 (see Fig. 8),and when the gear wheel 39 is rotated over a given angle by the forkedend 36, the other forked end 37 engages a pin 44 fixed at the undersideof the base stand A so as to release the forked end 36 from the teeth ofthe gear wheel 39 (see Fig. 9). Accordingly, a check paper feeding rod45 having rack teeth 46 along its one side geared with the teeth of thegear wheel 39 and inserted slidably in a transverse groove 47 formed atthe underside of the base stand A rs moved'toward the left side (in'Fig.2) over a given length when the gear wheel is rotated. If desired, thisfeeding rod may be arranged to move toward the right side. i

The check paper feeding rod 45 has attached at its left hand end a head48 having a paper clip 49 thereon (Fig. 13). The paper clip 49 has twoopenings 50 at the portion to catch the check paper. The head 48 hasalso two projecting parts 51 at the corresponding portion to theopenings 50. As the clipping end of the paper clip 49 is urged to press,by means of a spring 52,. against the head '48, the projecting parts 51enter the openings 50. When a check paper is caught by the clip 49, theprojecting parts 51 pushthe paper end into the openings 50, consequentlythe check paper will not loosen and come oli the clip. It is veryimportant to catch and hold the check paper in printing. In the printingoperation, a considerable shock is given to the paper, and the printingof letters or figures is done by a number of small notches on the matrix24 and the printing wheel 2. Hence, when the paper moves towards theleft hand side over a given length after printing one letter or figure,the paper will be detained by the matrix 24. This detaining force tendsto obstruct the regular feeding of paper, so that the letters or figuresare often printed at irregular intervals. According to the clip deviceof the present invention, however, perfect and satisfactory holding ofthe paper is obtained.

The check paperfeeding rod 45 may be modified as shown in Figs. 14 and15 so that its length may be varied to allow for varying widths of checkpaper. The check paper feeding rod 45 consists of a sleeve into which anadditional rod 53 is slidably inserted. The head 48 with the paper clip49 thereon is fixed at the end of the rod 53. The additional rod 53 hasa cavity 54 at the right hand end portion and therein is arranged aspring pawl 55 directed towards the head 48. The rod 45 has a hole 56,so that when the additional rod 53 is in the expanded position, the pawl55 engages with the hole 56 so as to retain the additional rod 53 inthat position.

A check paper pressing plate 57 has its rear end fixed on the rear endof the base stand Aand the check paper is loosely held between saidplate 57 and the base stand A. After printing one letter or figure thecheck paper caught by the clip 49 at one end is moved toward the lefthand side over a given length, and the next desired letter or figure onthe printing wheel 2 is brought into the lowermost position to becontacted with the ink roller 13 by the proper operation of theoperating wheel 4.

When the operating lever B is pressed downwardly to effect the nextprinting operation, the projecting part 25 of the operating lever isswung rearwardly about the pivot 1, and the push rod 29,,the guidemember 32 and the drive rod 34 are retracted by the action of the spring31 to a position as shown in Fig. 7 in readiness to make the next feedof the check paper. 1

When this check writer is not in use, the check paper feeding rod 45 iswithdrawn from the transverse groove 47 in the base stand Aand isinserted into a longitudinal receiving slot 58 in the base stand A asshown by a dot and dash line in Fig. 7, so that the transverse size orwidth of this check writer is reduced and it may'conveniently be carriedin -a pocket.
